Claims. (01. 128-491) This invention relates to oxygen administerin equipment.

An object of the invention is to provide equipment of the character described for administerin'g oxygen to apatient.

It is another object of the invention to provide equipment of the character described whereby the oxygen being administered may be diluted with air as required.

The equipment embodies a tent which may be closed about the waist of an adult patient so that the body of the patient above the waist will be completely enclosed within the tent and in case the patient is a small child the entire body of the patient may be enclosed. The invention also includes a novel type of ice cabinet which is also enclosed within the tent and the tent is provided with a top zipper for the admission of ice into the cabinet and a side zipper for giving attention to the patient in administering nursing care as well as a zipper for closing the tent about the waist of an adult patient.

It is a further object of the invention to provide, in equipment of the character described, a novel type of ice cabinet having upper and lower front openings with controlling shutters whereby the air enclosed within the tent may circulate through the ice cabinet and tent by convection.

In a preferred form of the cabinet it is provided with a plurality of lower openings controlled by separate shutters whereby the patient may be shielded from direct current and yet a sufficient circulation maintained.

The cabinet is equipped with an air meter so that the required proportion of oxygen and air may be admitted depending upon the requirements of the particular patient.

A further object of the invention is to provide a novel type of ice cabinet support which may be readily applied to, and removed from, the mattress spring beneath the head of the patient. This support is of such construction that it may be applied to the mattress spring or other mattress support, even while the mattress is on the support.

An important feature of the cabinet support resides in the fact that it may be quickly and easily adjusted to maintain the cabinet in proper upright position irrespective of the inclination of the mattress spring to which it is anchored A further feature of the equipment resides in a novel construction whereby no motors, fans or electrical equipment is required to circulate the air through the tent.

Other objects and advantages will be apparent from the following specification which is illustrated by the accompanying drawings, wherein- Flgure 1 is a side elevation of the equipment as applied to a patient.

Figure 2 is an enlarged, fragmentary, p rspective view of the equipment with the mattress and tent removed.

Figure 3 is an enlarged, fragmentary, vertical, sectional view taken on the line 3-3 of Figure 2.

Figure 4 is a vertical, sectional view of the cabinet taken on the line 4-4 of Figure 1.

Figure 5 is a perspective view of the foraminated ice container.

Figure 6 is a transverse, vertical, sectional view of the ice cabinet.

Figure 7 is a horizontal, sectional view of the ice container taken on the line 11 of Figure 5 and Figure 8 is an enlarged, fragmentary end elevation of the ice cabinet.

Referring now.more particularly to the drawings wherein like numerals of reference designate the same parts in each of the figures, the

numeral l designates the bedstead which may be of any suitable type and whereon is shown mounted the mattress supporting springs 2.

The end of the mattress springs atthe head of the bed is formed with transversely aligned hinges, as 3, whereby said end may be adjusted vertically to the desired angle as indicated in Figure 2.

This spring 2 supports the mattress 4 in the usual way, and includes a frame 2a of rigid material.

The numeral 5 designates, generally, the ice cabinet which is, preferably, substantially rectangular in horizontal cross-section although it may be of any selected shape. This cabinet is substantially enclosed on its sides, ends and bottom and contained within it and readily removable from it there is a foraminated ice container 6 which is shaped to fit snugly in the cabinet and which is formed with a cover I which forms also a cover for the cabinet. This ice container is provided with a top inlet opening for the introduction of ice.

In a preferred form of the ice container it has two vertical lengthwise partitions, as 9, 9, which are spaced apart and reinforced by an intermediate corrugated partion III. This arrangement has been provided to prevent the crushed ice from packing and to promote the circulation of oxygen through the ice cabinet. In a preferred form of the ice cabinet it is provided with an upper transverse opening II in its front wall which may be controlled, or completely closed, by a corresponding transverse shutter I2.

The front wall of the ice cabinet is also provided with a lower transverse opening l3 extending approximately from end to end thereof and associated with this opening there are a plurality of shutters, preferably three, to-wit an intermediate shutter l4 and end shutters l5, IS. The intermediate shutter I4 is considerably longer than the end shutters and it may be closed to shield the patient from direct current with the end shutters open to allow free circulation of oxygen.

If desired the lower opening l3 may be provided with an air filter l 6 for use in purifying the air of pollen and foreign substances when pa-v tients are being treated for asthma or similar diseases. This screen may be elevated to inactive position or lowered to active position as required. It will be noted from an inspection of Figures 4 and 6 that the ice container does not extend down to the bottom of the cabinet. Beneath the ice container the cabinet is provided with a transverse partition I! extending from end to end and side to side thereof and forming a bottom and within the space between said bottom I1 and the bottom of. the ice container there is a forwardly declining deflector l8 extending from end to end of the cabinet to deflect the down flowing air forwardly. This deflector is provided with a suitable number of openings to allow the water from the melted ice to pass through and this water is discharged through a suitable outlet nipple l9 which may be connected to a suitable discharge hose 20'.

Rigidly anchored to, and depending from, the ice cabinet there is a tubular anchor 2| the purpose of which will be hereinafter explained.

Novel means have been provided for supporting the ice cabinet which will now be described:

There isa transverse bar 22 shaped to flt onto the head end of the frame 2a, as shown in Figure 2 and secured to the ends of this cross bar are the upwardly converging brackets 23, 23 whose upper ends are turned into parallel relation, as shown in Figure 2. These upper ends are connected by cross rod 24 on which the bearing sleeve 25 is mounted to rotate; and upstanding from the sleeve there is 'a spindle 2B which telescopes into the anchor 2| and may be adjusted therein and secured at any selected point of adjustment by the clamp screw 21, said anchor and spindle forming a supporting standard.

There are the hooks 28, 28 whose lower ends are engageable with the depending flange of the cross bar at the head end of the mattress support and whose upper ends are externally threaded and extend through openings in the bar 22 and receive the clamp nuts 29 whereby the bar 22, and the equipment supported thereon, may be readily removed from or secured to the frame of the mattress support.

Secured to, and depending from, the sleeve 25 there is an elongated hasp 30 having a vertical slot 3| therein and between the brackets 23 there is a transverse bar 32 whose ends may be welded to said brackets and threaded through this bar there is an externally threaded adjusting rod 33 which works through the slot 3| and one end of which is provided with a retaining head 34. The other end of the rod 33 has a hand grip 35 thereon whereby it may be turned. The support for the ice box may thereby be adjusted so as '4 to maintain said box at all times in vertical position. This adjustment is necessary for the reason that the head end of the mattress spring and mattressmay be adjusted vertically for different inclinations of the patient and the ice box must be maintained, at all times, in vertical position so that the water collected from the ice will not spill out through the opening I3.

There are the flat retaining arms 36, 36. These arms are pivoted, at one end, to the respective ends of the transverse bar 22 so that they will swing on vertical axes. When in active position they extend forwardly underneath the mattress and thus form additional anchorin means for anchoring the ice box support to the mattress spring.

If the mattress is already in position on the mattress spring and it is desired to use the oxygen administering equipment while a patient is on the bed, the retaining arms 36 may be swung outwardly into alignment with the bar 22 and said bar secured in position. The corners of the mattress may then be successively raised and said retaining arms successively swung into position underneath the mattress, this without discomfort to the patient on the mattress; and, reversely, the oxygen administering equipment may be removed when its use is no longer desirable.

There is a transparent tent 31, formed of any selected material and designed to envelop the ice cabinet as well as the chest and head of the patient; and in case of a small patient it may envelop the entire body. It has a top zipper 38 for access to the filling opening 8 of the ice compartment, a side zipper 39 for access to the patient and a front zipper 40 for closing the tent about the waist of an adult or for completely enclosing a small patient. The tent should be of suflicient capacity to give the patient the required amount room.

The tent may be supported above the patient by means of a U-shaped supporting frame 4| the free ends of whose side arms embrace the top portion of the ice cabinet. These ends have the flattened portions 42 which are provided with rod hearings to receive a rod 43 which passes through the ice cabinet. One end of this rod may have a conventional head and its other end a is outwardly threaded to receive a wing nut 44.

The nut 44 may be loosened and the frame adjusted up or down to vary the capacity of the tent, as required, and the nut then tightened to maintain the frame in said selected position; or the zipper 40 may be opened and the frame moved into vertical, or substantially vertical, position to support the tent out of the way when removed from the patient, as indicated in dotted lines in Figures 1 and 8 and the nut 44 then tightened to maintain that position.

Oxygen may be admitted from a conventional oxygen tank at 45, through the outlet pipe 46. This pipe is controlled by the hand operated shut off valve 41 and it is connected into the ice cabinet through the hose 48 connected, at one end, to the pipe 46 and, atits other end, to the inlet nipple 49 of said cabinet. The outlet pipe 46 of the oxygen tank is equipped with a. suitable air meter 50 whereby air may be admitted and mixed with the oxygen as the nature of the affliction and the circumstances of the case may require.

In assembly the spindle 26 is inserted through an opening in the head end of the tent at the bottom and the tubular anchor 2| is then fitted down over said spindle and secured in place. The

tent, with zipper 40 open is-then brought up over the ice cabinet with the bottom of the tent down over the mattress. The zipper 40, therefore, should be made long enough so that the cabinet can be enclosed in the tent.

The equipment is especially useful in administering oxygen to infants and children as it can be nicely fitt'ed to a bassinet or child's bed.
